Ability to use previous placeholder value in expression

[naquad]

Illustrated with the following snippet:

snippet getter
    public function get${1:variable}()
    {
          return $this->`tolower(GetHolderValue(1))`;
    }

Basically whats need is the way to get to the other holders values. In this case I'm doing it with global function, but anyting will do. Thank you.

Unfortunatelly, it is hard to implement.

This feature would be invaluable!

It is implemented in deoppet.nvim.
So closing.
